(Ambiya') 21 : 32
وَجَعَلْنَا السَّمَاءَ سَقْفًا مَحْفُوظًا ۖ وَهُمْ عَنْ آيَاتِهَا مُعْرِضُونَ

And We made the sky a protecting canopy, but they are neglecting all those Signs.

Lord has created the sky in layers so that it will protect the earth from the harmful rays of the sun and stars, comets, asteroids, etc. Even though mankind is having the scientific knowledge about these, they can’t control the intrusion of mankind towards them which is affecting the sky and earth, and thereby the universe. It can only be controlled with Adhikr which is the Constitution of the universe. But the people of the last Messenger have become the Arabic Quran reading Fujjar who neither utilize Adhikr nor give It to others. Thus they are hurrying for the Antichrist and thereby the Doomsday. Only 1 in 1000 believer who testifies Adhikr utilizes all his will and power for propagating Adhikr to whole mankind aiming to extend the life span of the universe as explained in verse 2: 62. See explanation 1: 7; 2: 39 and 15: 16-18.
